i This invention relates to warping machine drives and controls for the same.

. .One'of theobjects of the invention is to provide a novel drive for a warping machine to the ends that less power than heretofore required may be sufiicient to drive one of said machines and that such a machine maybe driven witha minimum of vibration without any jars or jerks, to prevent yarn wound on a machine of the type mentioned from being broken and to allow the yarn to be wound on the machine at a uniform tension. I I V A further object of the invention is to provide control means for a warping machine that willenable the operator to stop it should he be at some remote point, as attendingto the spools, when the stopping operation becomes necessary.

Other objects of the'inventlon will be appreciated from reading of the following.

specification. 7 I The invention will be fully andcompre 'hensively understood from'a consideration of the following detailed description-when .read in connection with the accompanying drawings which form part of the application, with the understanding however, thatthe improvement is capable of extended application and is not confined to the exact showing of the drawings nor to the precise construction described and, therefore, such changes ,and modifications maybe made therefrom as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the r appended claims.

In the drawings:

F'g. 1 is an end elevation of a warping machine to whichthe mechanism of my invention is applied.

the mechanism shown in Fig.1 and taken approximately on the line 22 of Fig- 1,

parts of themechanism shown in Fig. lbe- Referring to the drawings for a more detaileddescription thereof, the numeral 5 indicates a rotatable spider-on which yarn is .motor 22. A helical spring 23 is secured to thelever l0 and to an endofa lever24;, which Fig. 2 is a fragmentary front elevation of wound, said spider being mounted on a frame 6. In order todrive thementioned spider at a uniform or steady rate,-I p'lace a belt 7 on a flange 8, mounted on -the spider, andtighten saidbelt by means of an idler pulley 9. mount-- .ed on a lever 10, which is pivotally nounted at 11, said pulley being'adapted to tighten the mentioned belt when pulled to the leftjby means of a link 12 pivotally secured at one' end to the lever 10 and'at'its other end to a bell crank lever 15 pivotally mounted atil6,

said bell crank. lever being adapted to be ac 1 tuated by a-treadle .17 running the width of the machine. The-mentioned drivingbelt-7, A

in additionto running on the idler pulley 9, runs on the pulley l8 mounted on a" shaft 20 associated with reduction gearing which is housed in a casing21,saidreduction gearing being adapted to'bedriven by an electric connects atits other end with an oil switch 25adapted to open and; close the circuitof the motor 22. Downward pressure on the treadle 17 is effective to close the [switch 25 in order pto startthe motor 22, a further downward movement of said treadlebeing re'quiredito movetheuidler pulley 9 into such position that it tightensthe belt 7 sufliciently to drive.

the spider 5, this featureenabling the motor l to pick up before it assumes the load. A releaseiof pressure on the mentioned treadle is effective to allow the idler pulley 9 to drop so that the belt is loosened to the point where itis ineffective to drive the spider.

Y A vertical bar 27 is pivotally connected at its lower-end to the bell crank lever 15, as

indicated by the numeral 28, and said bar-is adapted to slide in accordance with move ments givenit by the mentioned bellcrank. lever, through a retaining member .29 attached to the frame 6 of the machine. A depression ofthe treadle 17 sufficient to cause. the belt 7 to drive thespider, is effective to depress the vertical bar 27-so that a dog 30'may engage the upper end portion of the mentioned bar to hold the same depressed, the depressed bar being effective to hold the treadl e and its con- 4 .nected bell crank lever depressed to the posi tion required for tightening-the belt to the art in orderto enable the operator to stop the machine from any position he might be at in operating the machine, it being remems bered that the mentioned treadle'extends substantially from one end ofthe machine to the I other. It has of course been necessary, and

still is necessary to provide means whereby;

the operator may stop the machine in any position he may be, but'instead of using mech anism requiring him to keep his foot on the treadle in order to keep the machine running I have provided mechanism whereby the treadle is kept depressedfand whereby the operator, may; stop the machine in any posi tion where he may be located at the front of the machine. This mechanism comprises the bar 27 and dog 30.

The dog 30 is fixedly mounted on a shaft 32, mounted in bearings 33 and extending substantially through the widthof the machine.

Said shaft is adapted to be rocked by a con trol handle 35 which is slidableon the shaft so that the operator'of the machine may move the handle when he walks from one position to another. The operator therefore always has the control handle within reach so that he may stop the machine in any position he may be, it being readily seen; that by pushing'the inentioned'control handle toward the spider the dog 30 may be disengaged from the vertical lever 27 to allow the treadle .to rise and the idlerpulley 9. to fall to such a position that the beltis slackened sufficiently so that the belt cannot drivethe spider. The connection of the control lever 35 to the rock shaft 32 is best shown in Fig. 3, it being there shown that the mentioned shaft is providedwith a longitudinal groove 32a into which extends a pin 35a secured to the hub 35?) of the control handle.

I have also invented means. whereby a warping machine may be attended to by the operator, and stopped if necessary,.if the operator be at theback of the machine attending the spools. Said means is a remote control means and comprises a switch 37 in an electric power'circuit 38 adapted to allowcurrent to flow through a solenoid 39 provided with a vertically movable core 40, the upper end of which is attached to a chain 41, the latter being connected at its'upper end to an arm 42 rigidly connected to the rock shaft 32. vWhenthe switch 37 is closed, the solenoid 39 is energized and the core is drawn downwardly into the same, by which action the shaft 32 is rocked in a directionto cause the dog 30 to be disengaged from the vertical bar 27, the latter thenbeing free to rise with the result that the idler pulley 9 drops to slacken the belt 7 and become ineffective to drive the spider.

l/Vhat is claimed as new is:
